Sanitary Sewers

In areas where sanitary sewer systems are operated and maintained by the Oakland County Department of Public Works, final acceptance of the system must be rendered by the Oakland County Department of Public Works and the City of Farmington Hills before the system can be used for the service intended.

One item required for final acceptance shall be the submission of as-built plans to the City of Farmington Hills by the design engineer. As-built plans for the sanitary sewer system shall be defined as and contain the following information:

As-built sanitary sewer system plans shall indicate the offset of sanitary sewers from property lines and shall include, but not be limited to length of sewer, invert elevation, rim elevation, percentage of grade, manhole location, sewer material and joints used. An as-built profile drawing must also be provided for all sanitary sewer systems.

Locations shall be shown on the plans with an accuracy of + one (1) foot. In addition, the location of all building service leads must be indicated from the downstream manhole. The length of the lead and any riser information must also be indicated.

As-built sanitary sewer plans shall list the as-built quantities and the type, brand name and lengths of pipe used.

The City of Farmington Hills and the Water Resources Commissioner no longer accept record mylars. Digital copies of the plans in TIFF image files, burned onto a CD/DVD, must be submitted instead. The project engineer should submit three (3) copies of the CD/DVD, and two (2) sets of prints, signed and sealed, to our office for archives. A cover letter, signed and sealed by the registered professional who prepared the drawings, must be submitted indicating that the plans on the CD/DVD are the final as-built plans for the project.

Detention System

Upon completion of construction and prior to the final approval for the Certificate of Occupancy, as-built plans must be submitted for approval to the City of Farmington Hills by the design engineer. As-built plans for the detention system shall be defined as and contain the following information:

As-built plans of the retention system must include as-built grade contours, with adequate spot elevations to substantiate these contours. The high water and freeboard elevation and contour lines must be clearly indicated. The side slopes of the pond also must be clearly indicated. Also, as-built volumetric calculations must be shown to verify that this system was built as designed and approved by the City of Farmington Hills.

Storm Sewer

Upon completion of construction and prior to final approval of the storm facilities, as-built plans must be submitted to the City of Farmington Hills by the design engineer. As-built plans for the storm system shall be defined as and contain the following information:

As-built storm system plans shall indicate the offset of storm sewers from the property lines and shall include, but not be limited to length of sewer, invert elevation, rim elevation, percentage of grade, manhole location, sewer material and joints used. An as-built profile drawing must also be provided for all public storm sewer systems and private systems on sites larger than one acre.

Locations shall be shown on the plans with an accuracy of + one (1) foot.

As-built storm sewer plans shall list the as-built quantities and the type, brand name and lengths of pipe used.

Water Systems

In areas where water systems are operated and maintained by the Oakland County Department of Public Works, final acceptance of the system must be rendered by the Oakland County Department of Public Works and the City of Farmington Hills before the system can be used for the service intended.

One item required for final acceptance shall be the submission of as-built plans to the City of Farmington Hills by the design engineer. As-built plans for water main shall be defined as and contain the following information:

One item required for final acceptance shall be the submission of as-built plans to the City of Farmington Hills by the design engineer. As-built plans for water main shall be defined as and contain the following information:

As-built water system plans shall indicate the offset of water mains from property lines and shall locate gate valve wells, hydrants and all water system appurtenances from the nearest property corner. An as-built profile drawing must also be provided for all watermains 16" in diameter or larger. Locations shall be shown on the plans with an accuracy of + one (1) foot. In addition, all underground appurtenances, such as gate valve wells, meter pits, pressure reducing valve pits, etc., shall be located from the nearest hydrant that is connected to the same water main as the appurtenances. Locations shall be shown on the plans with an accuracy of + one (1) foot.

As-built water system plans shall list the as-built quantities and the type, brand name and lengths of pipe used. Hydrants, gate valves, etc., shall also be listed showing their type, brand name, and quantity. The location, size, manufacturer and model number of every restrained joint shall be noted.
